Abstract
Post-traumatic myositis ossificans (MO) is a benign hypertrophic ossification lesion which occurs occasionally after muscle contusion. A 15 years old footballer with a left vastus intermedius contusion had an unexpected increase of symptoms after 8 days of gradual recovery. His serial ultrasound scan showed signs of MO as early as 4 weeks. X-rays showed early changes of MO only after 4–6 weeks. MRI helped to identify the morphology and differentiate it from soft tissue malignancies. Usually the lesion is self-limiting responding to conservative treatment with return to play after 4–6 months. Extracorporeal shockwave therapy may be beneficial to provide symptom relief meanwhile surgery may be needed to treat residual large ossifications.
